EAVES-TROUGH.

SPECIFICATION forming part of Letters Patent No. 503,940, dated August29, 1893.

Application filed May 1, 1893. Serial No. 472,600. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS S. BONBRAKE, a citizen of the United States,residing at Decatur, in the county of Macon and State of Illinois, haveinvented certain new and useful Improvements in Eaves-Troughs; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon, in which- Figure 1, is a view showing a portion of thesheet from which a section of caves trough is made or formed, showingits construction before any folding is done. Fig. 2, is a view showing aportion of the sheet from which a section of eaves trough is formed, andillustrating the sheet partially folded, and the bead formed. Fig. 3, isan end view of the joint end of the section. Fig. 4, is a perspectiveview showing a portion of the eaves trough properly finished. Fig. 5, isa longitudinal section of the jointthrough line a:x Fig. 4. Fig. 6, is aview showing aportion of the eaves trough, and illustrating the raw endof the section. Fig. 7, is a view illustrating the position of the jointend of the bead, showing the same partially constructed.

The present invention has relation to eaves troughs, and it consists inthe different parts and combination of parts hereinafter described, andparticularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all thefigures of the draw- IIJOS.

In the accompanying drawings, A rep resents the sheets or sections ofmetal from which the eaves trough proper is formed, and are formed insections of any desired length. Upon one side of the section A, isformed the head or roll a, said bead being formed in the ordinarymanner, as hereinafter described. One end of each of the sections A, isprovided with the lip or extension I), which lip or extension is formedby cutting the openings or notches c and c, which openings or notchesare located and arranged substantially as shown in Fig. 1; whichopenings or notches also leave upon bead edge of the section A, theextension B 5 the inner edge of said extension B, being provided withthe inclined edge cl. The grooved end of the section A, is cut at anangle; or in other words is cut diagonally across the end of thesection, substantially as illustrated in Fig. 1, and is so formed forthe purpose of providing a guide for entering the raw end of a sectiondesigned to be received into the groove e, which groove is formed ashereinafter described. The groove e is formed by bending a portion ofthe sheet or section A, over and upon itself, at a point on line y-y,Fig. 1, and then giving to said bent over portion a second fold on line2z, Fig. 1, which folds form the groove 6, and the flange or guide f. Itwill be understood that by pro viding the extension I) and forming thesame as shown in Fig. 1, when the bead a, is formed, said extension willassume the position illustrated in Fig. 4, when the joint end of thetrough proper is finished.

By providing the extension B, and locating the same as illustrated inFig. 1, it will be brought into proper position to be folded over thebead a, as illustrated in Fi 4, thereby giving double strength to thebead proper at its joint end.

For the purpose of securely holding the end of the bead a, and theextension B, in close contact, and at the same time preventing theextension B, from springing out of its proper position, the lips g andg, are bent over the open end of the extension B, as illustrated in Fig.4, which completes the grooved end of the trough; and for the purpose ofholding the opposite end of the extension B, in close contact with theinner faces of the trough, it may be soldered to the section A.

It will be understood that by folding the lips g and g, as illustratedin Fig. 4, and providing the extension I), and forming the same asillustrated, it will act as a guide for entering the end of the beadformed upon the section, to be attached to its adjacent section. Bygiving a double thickness to the bead proper, at the point where thejoints are formed, and entering the adjacent bead within that portion ofthe bead having a double thickness of metal, a very rigid connectionwillbe formed at the joints of the eavestrough 'For the purpose ofassisting in entering the opposite side of the section, from thatprovided with the bead, a portion of the entering end of the section A,is bent down upon itself, as illustrated at b, Fig. 6.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the sheets or sections A, provided with the lip orextension I), and the extension B, the bead a, the groove e, the flangeor guide f, and the lips g and g, bent over the extension 13,substantially as and for the purpose specified.

2. The combination of an eaves trough, provided upon one side thereof,with a bead or roll, the extension B, located upon the outer side andaround the bead a, the lip or extension 12 the groove e, the guide orflange f, and
